[PATCH core-updates] gnu: python-pytest: Fix failing test_raising_repr.

[Josselin Poiret]

* gnu/packages/patches/pytest-fix-unstrable-exception-test.patch: Add new
patch from upstream.
* gnu/packages/check.scm (python-pytest): Use it.
* gnu/local.mk (dist_patch_DATA): Register it.

Hey Andreas and Kaelyn,

This should also fix it without bumping python-pytest to a new version (since it
has so many dependents, don't want to introduce new breakage now).

Best,
Josselin
